Chronos staggered, clearly affected by Saitama's punch. But instead of faltering, he roared in fury, his form beginning to shift and distort. "You insignificant worm!" Chronos snarled, his voice shaking the very ground beneath them. His body started to twist into something even more monstrous, absorbing more energy from the rifts around him.

Teri realized they had to close the rifts before Chronos could gain more power. "Kei, Ignis! We need to seal the rifts, or he'll only get stronger!"

Kei's eyes glowed as she summoned the celestial light, her wings spreading wide as she began to channel her power into the rifts. "I'll need time to close them all."

Ignis stood by her, her flames blazing even hotter. "I'll cover you. No one's getting through."

As Kei worked to seal the rifts, Goku and Vegeta joined Teri and Saitama in the fight against Chronos. Despite his overwhelming power, Chronos was beginning to struggle. His attacks became more erratic, his energy unstable.

But even as the rifts started to close, Chronos unleashed one final surge of power. "If I cannot control the multiverse, then I will destroy it!"

With a violent explosion of dark energy, Chronos summoned a vortex large enough to consume entire universes. The ground quaked as reality itself began to unravel.

"We have to stop him now!" Vegeta shouted, powering up to his maximum, his energy purple and fierce.

Teri's eyes narrowed as he summoned all the celestial power within him. "No matter what happens, we end this here."

In one final, desperate move, Teri, Goku, Vegeta, and Saitama launched themselves at Chronos, their combined power clashing with his. The battle was fierce, the sky above them splitting as the very laws of physics bent under the strain.

And then, with a final, earth-shattering blow, the rogue Celestial was defeated. Chronos let out a deafening scream as his body disintegrated, his dark energy fading into nothingness. The vortex collapsed in on itself, and the rifts that had threatened to destroy the multiverse were finally sealed.
